Have you heard about the Polish Train company, Newag, and the bullshit it turns out they got up to?

So, the regional rail operator Koleje Dolnośląskie bought some Newag Impuls back in 2016 . In late 2021, some of them need to have major maintenance done, as they've been in service a while. So the company SPS (Serwis Pojazdów Szynowych) gets the contract to fix them. They basically take the train apart, replace a bunch of it, following all the rules in the documentation Newag gave them, and... it won't move. The train says everything is fine, the brakes are off, there's plenty of power, but you push the throttle up and it won't move.

SPS spends a while trying to figure out what the fuck is wrong, with no luck. So they hire some hackers from the Polish security group Dragon Sector. Dragon Sector figures out how to get into the code of the computer system that runs the train, and OH MY GOD.

So it turns out there's a secret train-lock system. If it's on, the train won't move. This will be triggered in some situations you might think are normal: the clocks are wrong, the serial numbers of the various parts have changed, and a firmware mismatch between the main computer and the power system. Now, the fact that it makes sense to not run the train in these situations until someone can check it? that doesn't extend to the fact the train uses a SECRET lock system, rather than just popping up an error message telling you what's wrong. There's also the problem that while these are all potential error problems, they can't be cleared by anyone with the technical manuals, which are supposed to cover everything about how to run these trains. Only Newag themselves can reset this system.

Which, you know, keeps SPS from properly fixing them. Only Newag can fix them now, but not because SPS lacks any technical ability, but because Newag sabotaged their own trains. But don't worry: it gets worse.

So now that Dragon Sector knows what's happening, they get to look at other trains. It turns out the trains aren't all running the same software, and there are other tricks in there.

One of them is a "how long has the train been stopped?" check. If the train hasn't hit 60 km/h in 10 days, the train locks itself and won't move until Newag can clear it. So, like, if a train is ever out of service, like it's going to a repair place... it'll break itself. Unless the repair place is owned by Newag.

But two of the trains go further: See, these trains have GPS built in, right? You may be able to guess where this is going...

THEY JUST MAKE THE TRAIN CHECK IF IT IS PARKED AT THEIR COMPETITORS' REPAIR YARD AND BREAK ITSELF IF IT WAS.

The sheer audacity of this move. This is frighteningly bullshit anti-competition self-sabotage.

This has, obviously, made some parts of the Polish government to start investigating this. Newag may be (and hopefully will be) in a lot of trouble.

For more info, there's a great video of a presentation by the three people from Dragon Sector who did the hacking, which was presented at the 37th Chaos Communication Congress in Germany.

Ars Technica also has an article on it, but it predates the presentation so it doesn't have some of the later details.

Anyway, the good news is that in the end the hackers at Dragon Sector were able to unlock most of the trains: A few had additional trickery that they didn't want to hack around, because it might break the train's certification. For the others, they discovered undocumented "cheat codes" in the software that they could use to bypass the secret lockouts... presumably the same ones that Newag would have used when they "repaired" trains.

🇵🇸 Help Marah's family restore their lives!

I want to introduce you to the Baloushaa family, who are currently living in Gaza. The family lived in a beautiful house, and Mahmoud owned a shoe store that was doing well. Marah (@freepaleatine95) was studying computer engineering at Al-Azhar University, a subject she has a lot of interest and passion in. Mahmoud's business was successful and Marah's studies were going excellently. Their parents were proud of them for all they accomplished, and they had great dreams for their futures.

But even before the recent aggression starting on October 7th, this family had experienced profound loss. They lost their older brother in 2006, a stark reminder that the violence inflicted on Palestinians did not start within the past year, but has been a continued effort to wipe out their people. With the most recent escalation in violence, this family has been forced to experience loss again. They lost the beautiful house they lived in, and they lost the kittens that they cared for dearly. Mahmoud's business was destroyed as well as Marah's University and their lives have been frozen.

The picture above is their current living situation, they are trying to survive without proper shelter, exposed to the weather and illnesses. Their mother and father both suffer from diabetes, and their father has high blood pressure, the medicine for which is near impossible to obtain in Gaza. As winter approaches and the temperature drops, they will need proper clothing, blankets, and a heater. Their ultimate goal is to move the family to Egypt so they can access proper care for their parents, Marah can continue university, and they can rebuild their lives.

The funniest possible outcome of all these Google antitrust disclosures re: deceptively re-writing people's search queries in order to maximise Google's ad revenue would be if the corporations that paid for those ads decide that Google has been defrauding them the whole time. The ultimate "bite each other's dicks off" scenario.

Whats the opposite of gothic? I'm in love with comp sci anti-gothic where it's just people being surprisingly polite and nice and funny through computers. A program's first lines are always "Hello world!". SMTP protocols apparently say "hello, pleased to meet you" to each other to establish a connection with a handshake. Python has a different version called Andaconda, which has a smaller version called miniconda. C++ is just C continuously improving on itself, because the ++ operator means to add one onto a previous value, and C# is two ++ stacked on top of each other. Lawmakers have to talk about the ethics of saving "cookies" to computers because one guy liked fortune cookies and decided to call them that. The internet itself wasn't created with security in mind because it was just meant to be a way for a group of people who trusted each other using it to send each other information, and so on, and so forth
